SELF-RETAINING SPLINT.

SPECIFICATION forming part of Letters Patent No. 602,917, dated April 26, 1898.

Application filed June 3, 1897. serial No. 639,358. (No model.)

To all whom; it may concern.-

Be it known that I, BERNARD SCHEINKMAN, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Self-Retaining Splints; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

The purpose of my invention is the prod action of a self-retaining splint which shall be especially adapted for use in certain surgical cases.

With this' end in viewmy invention consists in constructing a splint having two longitudinal plates united at the ends and provided with a flexible tubal sheath for retaining the said plates in contact with the part or organ when the splint is in situ.

It further consists in so constructing the splint that the sheath when applied will automatically be held in place.

Figure 1 is a view of my splint in side elevation, the tubal sheath being removed from the plates. Fig. 2 is a plan view of Fig. 1, but with the free end of the tubal sheath entirely extended. Fig. 3 is a top plan View of the splint, showing the tubal sheath in process of being rolled over the plates. Fig. 4 is a section of Fig. 3, taken on line E F and looking toward the right. Fig. 5 is a section of Fig. 2, taken online A B. Fig. 6 is a cross section of Fig. 2, taken through the tubal sheath on line C D.

Referring to the drawings, the numerals 2 and 3 designate the elongated plates, each concavo-convex in section, more or less flexible, and made of any suitable material. I prefer in practice to form the middle layer 5 of hard or vulcanized rubber and the outer and inner layers a and 6 of soft rubber or other fabric. At the point 8 the plates are integrally united, as shown, and constitute the wall of a tube. IVithin the opening thus formed by the union of the plates is permanently secured one end 13 of the tubal sheath 9. This sheath is preferably made of thin rubber or other elastic material. The extreme ends of the united plates and tubal sheath are clearly illustrated at 12 and 12.

The edge 11 of the free end of the elastic sheath is thickened throughout its circumference by increasing the quantity of material, so as to constitute an elastic core, or a separately-made elastic core may be inserted during the process of manufacture. This core 11, when the tubal sheath is applied, fits within the recesses 7 7 formed at the free ends of the plates, as shown by dotted lines in Fig. 3, and holds the parts in their proper relative positions.

To apply the splint, the plates 2 and 3 are separated and the integral part passed over the part or organ as far as desired. The tubal sheath is next rolled inwardly, (see Fig. 1,) as shown at 10, until the roll approaches the ends of the plates, where they are united. Then the tubal sheath thus rolled is passed over the ends of the plates and unrolled to the position in which the elastic core of the sheath fits within the recesses 7 7.

While I have shown the two plates entirely separated except at their extreme ends, they may, if desired, in practice be integral or united, as from 8 to 14, Fig. 2, without making a substantial departure. Other colorable changes may also be introduced and the forms of the several parts modified as experience may dictate.

As thus constructed, it will be seen that I have produced a very simple and cheap splint especially adapted for use as hereinbefore set forth and which will,when in situ, be retained automatically.

hat I claim as new, and desire to secure by Letters Patent, is

1. The herein-described splint consisting of the plates 2 and 3 connected to each other at the ends; and the tubal sheath 9 for embrac ing and confining the plates; substantially as and for the purpose set forth.

2. The herein-described splint consisting of the plates provided with the recesses 7, 7, adjacent their free ends; and the tubal sheath having an elastic core 11 for holding the said sheath in position; substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

BERNARD SGHEINKMAN.
